My guest this week is Eric Sorensen, the CEO of Panagora asset management, which manages more than $46B for clients across a variety of strategies.
 Eric began his career serving in the Air Force as both a pilot and instructor in high-performance jet aircraft. He then accumulated 40 years of quantitative research and investment experience, with a Ph.D. along the way.
 Please enjoy our conversation on the changing landscape of quantitative investment strategies.
